New forum for Elmer/Ice

Hello Elmer/Ice, at the EGU 2013 Elmer/Ice splinter meeting (see http://elmerice.elmerfem.org/wiki/doku.php?id=courses:firstmeeting for presentations given there), there was the request to have a documented channel for Elmer/Ice specific questions and answers. The mail-list was rather not considered...

Re: Free-Surfaces and partitioning

Hi Jean, I do not really think that there is an issue, if one of the partition is not containing any nodes of the FreeSurfaceSolver. I made a short test of the test-example trunk/fem/tests/freesurf_ltd, which - admittedly - only has one free surface at the uppermost y-coordinate layer. I split in th...

Re: 2D modelers

Hi, the most easiest way, if you already have the GMSH mesh, is to export it to a .msh (simply under Mesh-> Save in GMSH; lets assume under name.msh) file and then create a ready made Elmer file using ElmerGrid (standalone outside ElmerGUI) ElmerGrid 14 2 name.msh -autoclean That should create you a...

Re: Advection-Reaction Equation (Discontinuous Galerkin) Problem

Hello, do not know about periodic BC's. A good idea would be to replace Variable name Density to something else, as Density is a reserved name for the material property. The following file produces something - not sure what, though: Header CHECK KEYWORDS Warn Mesh DB "." "line" I...

Re: compiling with ifort compiler

Hello, sorry, that this comes with such a vast delay. Nevertheless, I thought it might be good to share this script that has been written by my colleague Olli-Pekka Lehto as the problem you described persisted and has a workaround in the attached script. This is a compilation script that worked for ...

Correction to previously sent message:

Try

Code: Select all

Dump system Matrix = String "TheFilename.suffix"
instead.

Re: Mass Matrix

Could you then try to cast it, i.e., write

Code: Select all

Dump Mass Matrix = String "TheFilename.suffix"
instead. Does that help?

Best Regards,

Thomas

Re: No results for Heat Flux

Hello Mat, I guess the no-show of your flux might be connected to the fact that the VTU output is executed as "After Timestep" and the Flux computation as "After All" - make sure that the Flux is computed before the output. What though puzzles me from your output is, that your Fl...

Re: Mass Matrix

Hi, Do you want to have the system matrix written out in ASCII? If this is your goal, a simple Dump system Matrix = filename in the solver section should do it. This was explained in the 6.2 Release Notes http://www.elmerfem.org/forum/viewtopic.php?f=11&t=1443&p=4290&hilit=Matrix+dump#p4...
